T o all whom it may concern:

Be 1t known that 1, Howl-inn G1nn1NGs,

Illinois, have invented a new and useful 1mprovement in Heaters, ofwhich the following is a specification.

My invention relates to a heating attachment for use in connection withlamps or gas-burners vfor deflecting the heat produced thereby, toeiqfect its distribution throughout the atmosphere and thus utilize theheat `from a lamp or gas jet for heating purposes.

One of my objects is to provide a deflec tor of the class referred towhich shall be simple of construction, and inexpensive to manufacture,and by which the heat from a lamp or gas-burner to which it is attachedmay be deflected downwardly in large volume and with force, thereby tomix the heated air with the atmosphere below the lamp.

A further object is to provide a construction having a reflector for thelight from the flame, and having means for collecting the soot.

Referring to the accompanying drawing- Figure 1 is a view showing myimproved heater seated on the chinmey of an incandescent gas-burner, theview of the deflector being in vertical section taken at the line 1 onFig. 2 and that of the burner being in elevation; Fig. 2, a bottom planview of the de- 'flector; and Fig: 3, a broken top plan view of thesaine.

4 is an annular drum preferably constructed of sheet-metal and having anouter wall or shell 5 of frusto-conical form flanged inwardly at itsupper and lower edges,` an inner wall or shell 6 likewise offrusto-conical form and forming a space 7 between it and the outer shelland a top-plate 8 overlapping the upper flanged edges of the shell 5 andsecured thereto as by a circular series of touffues 9 stam ed out of theshell 5 and b. passing through openings 1n the top e. The

inner shell Vfits against the top-plate 8 and is held in position at itsupper edge by abutment against the edges of the upper flange of theshell 5 and at its bottoni edge by engagement with an overlapping flange'l0 on the lower 'flanged portion of the shell 5.

11 is a series of pipes in the annular space 7 arranged longitudinallythereof, and fastened to and opening at their upper ends through theinner shell near its top, and at their lower ends fastened in andopening through the flanged lower end of the outer shell to formdownward passages or flues for the heated air and products of combustionfrom the top of the interior of the inner shell to the lower part of thedevice.

Openings 12 in the lower flange of the outer shell communicating withthe space 7 and intermediate of the pipe-openings may be provided, asshown, through which openings air may enter tht` space 7 and bedischarged therefrom in a heated condition.

l 13 is a frame fastened to the drum and by which the device is adaptedto be seated upon the chimney 14 of a gas burner 15, or lamp, as shownin Eig. 1. As shown, it is of wire, and comprises legs 16 and a top ring17I to which the legs 16 are secured at their upper ends; the lower endsof the legs being inturned as represented at 1S, to engage openings 19in the inner shell for supporting the drum upon the chimney 1.4.

The heat rising from the burner passes upward through the chimney andaround it until it reaches the top of the heater, 'from which it isdeflected into the pipes and downward through theln and out at theiropenings in the lower portion of the drum, the currents of heated airbeing illustrated by the arrows in Fig. 1. By thus deflecting the heatedair and products of combustion, a constant stream of air and hot gaseousproducts of combustion is directed downwardly with considerable force toa point on a plane some distance beneath the burner, where it spreadsout and .mingles with the surrounding atmosphere, thereby raising itstemperature. Furthermore, the upper closed end of the drum serves tocollect the soot which in the case of imperfect combustion rises `fromthe flame, and thus prevents its distribution throughout the room andits lodgrnent against the ceiling. In addition to the functions juststated the device, by providing a polished surface on the interior ofthe inner shell, serves to deflect the light downward and concentrate itbelow the flame, thereby greatly enhancing its usefulness for readingpurposes.

What I claim as new and desire to secure by Letters Patent is- 1. Aheat-deflector of the character set forth comprising a drum having aninner wall and an outer wall, said drum being provided with openings inits lower end and with openings in its inner wall near its upper end,and pipes between said walls connecting said upper openings with saidlower openings, for the purpose set forth.

2, A heat-deflector of the character set forth, comprising an annulardrum having an inner Wall and an outer wall, said walls being concentricwith each other and forming an annular space between them, said drumbeing provided with openings in its lower end and with openings in itsinner wall at its upper end, and pipes between said walls connecting theupper openings with the lower openings, for the purpose set forth.

3. A heat-deflector of the character set forth comprising an annulardrum of frustoconical form closed at its top and having an inner walland an outer wall, said walls being concentric with the other, andhaving' an annular space between them, the drum being provided with aseries of openings in its lower end and with a series of openings in itsinner wall at its upper end, and pipes l connecting the openings in theinner wall with lower openings, for the purpose set forth. 4. Aheat-deflector of the character set forth, comprising an annular drum offrusto-V conical form closed at its top and having an inner wall and anouter wall, said walls being concentric with each other, and forming anannular space between them, the druml being provided with a series ofopenings in its lower end and with a series of openings in its innerwall at its upper end, pipes connecting the openings inV the inner wallwith lower openings, and a frame secured to the drum adapted t seat thedeflector upon a chimney, whereby the heated air and products ofcombustion rising from the lamp are deflected downwardly through thepipes and discharged at the lower end of the drum, and whereby openingsare providedgin the lower part of the drum for permitting air to entersaid annular space and be discharged therefrom in heated condition.
